Save status_override and priority_override values during rebuild

I should make it clear that you shouldn't ever need or want to run the rebuild except for when you first install the module if you want all your data in the table right away. It is strictly a 'last-resort' kind of thing that should be done. I've added a warning on the page that says either "Your sitemap is up to date and does not need to be rebuilt." or "A rebuild is not necessary. If you are just wanting to re-create the sitemap files, you can <a href="admin/reports/status/run-cron">run cron manually</a>."

I have been looking into creating a temporary table for saving the custom values (priority and status) before dropping the data and then re-adding the data back in. I've also added an additional warning that says "You will lose all custom priority values for your links."

MM I've found that unless I do a complete rebuild any new nodes created have a 0.0 priority level. Then once I "rebuild" they are set to their appropriate level. Then everything is fine after that, this has been the same behaviour since I noticed the last 2-3 updates.

Moving this to a task as this is the current expected behavior.

Tagging as beta blocker.

I want this to be an alpha blocker.

This has been officially fixed with http://drupal.org/cvs?commit=303260 ! HOORAY!
